>I have a checkbox on a form and I would like that checkbox to be unchecked if the value in the field is either zero or null. Currently when the value is null it shows the checkbox in the third state and it is confusing users. I thought there was a way to just have the checkbox behave with two states checked or unchecked but I can't seem to find the property.

You can set Checkbox.Value programmatically, e.g.:

IF ISNULL(mytable.myfield)
  Thisform.Check1.Value=0
ENDIF
